This will inflate four boards on one charge. The carry case is decent quality. It's super nice to not have to inflate my board in the parking lot! I have recommended this charger to others because I am so happy with it.

I used it once and found it a little confusing to use. Once I figured it out it was fine. Fast forward a year and it charges fine and turns on but won't pump... so now it's a very expensive battery with no other use.

Went through 3-4 returns on Amazon looking for a low pressure pump that will actually read the 3-3.5psi needed for an inflatable boat/dinghy. This worked great, pumped to 3psi exactly and shut off. Everything about this was well though-out. The carry case that holes the tips and hose is very nice, I like how it came with an battery terminal adapter with battery leads just in case. The battery itself seems great, more than enough for my BRIS 10.8. Excited to get a lot of use out of this.

Pump is greatInflates quickly, auto shut-off, battery lasts well, includes Leafield C7 and D7 adapterOne point off for the hose. It is very stiff and awkward to use, and the boat side doesn’t rotate requiring the hose to be removed at the pump side so the hose can be attached to each valveStill happy with it overall

My 1st was a corded model was good but to much trouble as I had to have rafts close to van. 2nd was 1st generation and was a great improvement over the corded model. Now this one which has lithium battery, digital screen that shows battery life, pressure and such. They also made the hose so they screw on the pump, this makes it so they don’t pop out when pressure get high. Like auto shut off, can set pressure you want and work on other items while raft is filling. Also like that battery can be charged with cigarette lighter socket. My hope is that this new model will have better durability for the electronics as that was a weak point in old model.

Battery has no issue inflating a 12.5 boat, was down to 89% after completely inflating. Very portable, nice carrying case. The automatic shut off and no need to plug it in make this a fantastic pump. My only suggestion would be to separate the power/start pump button. It works fine but the difference between turning on the power/pump is a bit tricky. I find that half of the time I am turning off the pump instead of activating the inflation. Overall highly recommended.

Love this pumpBlew up my 2 sups quickly and efficientlyMake sure you have correct spacer, and its on tightHad plenty of battery life left after 2 boardsLove the case too
